Metro Manila (CNN Philippines) — The Ombudsman on Monday said will not initiate its own investigation into Senator Leila De Lima and her alleged involvement in the illegal drug trade inside the New Bilibid Prison.

"Lahat naman allegations itong mga ito eh. Wala pa namang lead talaga na that would prompt us to initiate our investigation," Morales told reporters on the sidelines of a forum. ("All these are allegations. There are really no leads that will prompt us to initiate our investigation.")

De Lima is facing allegations of having abetted the illegal drug trade during her term as Justice Secretary, and for having received payoffs and funding for her senatorial bid from high-profile inmates in Bilibid prison.

Two complaints against De Lima have been filed with the Department of Justice by the anti-crime watchdog Volunteers Against Crime and Corruption and by former subordinates of the senator from the National Bureau of Investigation.

The complaints charged De Lima for allegedly violating the Dangerous Drugs Act.

Another complaint against De Lima was filed last week by the police chief of the town of Albuera in the central Philippine island of Leyte with the regional office of the Ombudsman in Tacloban. Tacloban is capital of Leyte.

Morales said she will await the results of the investigation by the Ombudsman's regional office.
